v1.6.4

Changed

• Renamed GitHub Workflows from Distribution to CD and Version test to CI.
• Now caching the VapourSynth installation in GitHub CI workflow.
• Now directly loads a tensor from the VideoFrame data directly, without numpy as a middleman.
• Reduced overall numpy use for Tensor<->VideoFrame operations.
• The half parameter/options have been removed entirely and replaced with automatic infer based on
  input bit-depth. You must explicitly use RGBS if you want FullTensor (float32). Integer and RGBH
  inputs will be converted (if needed) to float16 (HalfTensor) automatically.

Removed

• Removed EOL Python 3.6 from CI Workflow.
• Removed unused infer_sequence method from EGVSR arch.
• Removed unused options and code from frame_to_tensor.
• All manual tensor deletion statements have been removed, they do not seem to help with VRAM.
• The overlap reduction code per-recursion has been removed. The overlap will now always stay
  at the value first provided.

Fixed

• Fixed a big Memory leak, that I still don't know exactly why it happened.
• Fixed minimum Python version listed under Installation docs.
• Improved the accuracy of clamping max size value to an equation on the exact bit depth.
  This fixes the accuracy of RGB 27, 30, 36, and 42.
